What is the minimum number of nighttime staff required for a home with 15 or fewer residents from 10pm to 7am?

In California, the regulations governing Adult Residential Facilities (ARFs) stipulate that for homes with 15 or fewer residents, at least one staff member must be on duty during the nighttime hours. The regulation allows for the possibility of having one staff member present while also designating another staff member to be on-call. This approach ensures that while there is a staff member available to respond to immediate needs, additional support can be summoned if necessary.

Maintaining one staff member on the premises for homes with fewer residents, particularly during midnight hours, aligns with ensuring the safety and well-being of residents who may require assistance during the night. This arrangement provides coverage while keeping operational costs in check, recognizing that a smaller facility may not necessitate a larger staffing presence under situations with fewer residents.

As a result, the correct answer accurately reflects the requirements and considerations for staffing in such residential environments, acknowledging the balance between available support and the specific resident population size.
